Hybrid Microgrid Controller: Solar, Battery and Load Priority

Approx. component budget: Rs. 10,000 - 16,000

Objective

Manage power flow between solar, battery and grid supply by priority rules and measure how much grid energy is saved.

What you will build

A small DC microgrid with a solar panel, a battery, a grid-simulating supply, controllable loads, power measurement at each node and a controller that decides the power flow and logs everything.

Results you can expect

• Power flow vs time at each node
• Battery state of charge
• Grid energy saved
• Load shedding events
• Behaviour under a sudden source loss

What you will learn

Microgrid control, energy management and priority logic, a growing field in renewable energy systems.

Tools and notes

ESP32, several INA219 sensors, relays or MOSFETs, battery, solar panel, dashboard, Excel. Keep the system at low DC voltage and use fuses on every source.

Resume points from this project

• Built and tested Hybrid Microgrid Controller: Solar, Battery and Load Priority; objective: manage power flow between solar, battery and grid supply by priority rules and measure how much grid energy is saved.
• Measured and analysed power flow vs time at each node and battery state of charge; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
